Objective: Accurate and rapid diagnosis of Coronavirus Disease-2019 (COVID-19), which started in December 2019 and caused a pandemic in a short time, is necessary for effective epidemic measures. Most infected patients develop an antibody response within 14 days. Serology tests based on antibody measurement are useful in understanding the prevalence in the population as well as supporting the diagnosis. In this study, it was aimed to evaluate COVID-19 antibody positivity in factory workers.

Methods: The results of 6836 factory workers who were sent to our hospital for COVID-19 antibody screening between August 2020 and September 2020 were evaluated retrospectively. Sera obtained from blood samples were studied by chemiluminescence immunoassay method. Age and gender data from demographic characteristics were also included in the study.

Results: A total of 6836 people with a mean age of 37.6 ± 10.1 years were included in the study. COVID-19 total antibody positivity was detected in 554 (8.1%) of factory workers. There was a significant difference in the mean age between the positive and negative groups formed according to the COVID-19 total antibody results (p=0.008). When the distribution is made according to the COVID-19 antibody results, the greater part (6.2%) of the people who were found to be positive had a low level of positivity. There was also a significant difference in the COVID-19 total antibody results between age groups (p=0.002).

Conclusion: The detection of COVID-19 antibody positivity at a rate of 8.1% in factory workers in the early period of the epidemic shows that serological tests can be useful in surveillance scans to determine the size of the epidemic.
